Load Mission 5: Siwa Oasis, equip the Panzerschreck RPG, and select any difficulty except Authentic. The Authentic difficulty does not feature in-game saves, which will prevent you from using this exploit. Skip the cutscene so the personnel truck is in range of your RPG. When the mission begins, run into the field, pause the game, and select the "Save Game" option. Then, destroy the personnel truck, pause the game, and select the "Load Last Save" option. Keep destroying the personnel truck to get 100 XP approximately every four seconds. Repeat this process as many times as desired.

Easy "I Siwa You Did There" achievement

In Mission 5, wait until your target collects the intel. He will start walking around the map. Follow him until he arrives at a fountain. On one wall is scaffolding with a rock on top. Wait until your shot is covered, then aim for the explosive barrel at the bottom of the scaffolding. The construction will collapse and bury your target, and you will get the "I Siwa You Did There" achievement. If you get spotted and he stops walking (and will not continue after you hide), try attracting him to the location step-by-step by throwing stones.
